■When the slip indicator flashes and a warning buzzer sounds
This situation occurs immediately while VSC is activated. Always drive carefully.
Reckless driving may cause an accident. Exercise particular care when the indica-

■Replacing tires
Make sure that all tires are of the same size, brand, tread pattern and total load
capacity. In addition, make sure that the tires are inflated to the recommended tire
pressure level.
The ABS and VSC systems will not function correctly if different tires are fitted on
the vehicle.

●MP3 and WMA playback
When a disc containing MP3 or WMA files is inserted, all files on the disc are first
checked. Once the file check is finished, the first MP3 or WMA file is played. To
make the file check finish more quickly, we recommend you do not write in any
files other than MP3 or WMA files or create any unnecessary folders.
Discs that contain a mixture of music data and MP3 or WMA format data cannot
be played.
●Extensions
If the file extensions .mp3 and .wma are used for files other than MP3 and WMA
files, they will be mistakenly recognized and played as MP3 and WMA files. This
may result in large amounts of interference and damage to the speakers.
●Playback
• To play MP3 file with steady sound quality, we recommend a fixed bit rate of 128 kbps and a sampling frequency of 44.1 kHz.
• CD-R or CD-RW playback may not be po ssible in some instances, depend-
ing on the characteristics of the disc.
• There is a wide variety of freeware and other encoding software for MP3 and WMA files on the market, and depending on the status of the encoding
and the file format, poor sound quality or noise at the start of playback may
result. In some cases, playback may not be possible at all.
• When files other than MP3 or WMA files are recorded on a disc, it may take
more time to recognize the disc and in some cases, playback may not be
possible at all.

Microsoft Corporation in the U.S.A. and other countries.

With some headphones generally available in the market, it may be difficult to catch
signals properly. Lexus recommends the use of Lexus genuine wireless head-
phones.
Please contact your Lexus dealer for further details.
■Vo l u m e
●Adjust the volume when you connect the headphones to the jack. Loud sounds
may have a significant impact on the human body.
●Conversational speech on some DVDs is recorded at a low volume to emphasize
the impact of sound effects. If you adjust the volume assuming that the conversa-
tions represent the maximum volume level that the DVD will play, you may be
startled by louder sound effects or when you change to a different audio source.
Be sure to adjust the volume with this in mind. An insulating sheet is set to prevent the bat-
teries from being discharged. Remove the
insulating sheet before using the remote con-
trol.

●DVD video discs: Digital Versatile Discs that holds world’s standard video. DVD
video discs have adopted “MPEG2”, one of the world standards of digital com-
pression technologies. The picture data is compressed by 1 /40 on average and
stored. Variable rate encoded technology has been adopted in which the volume
of data assigned to the picture is changed depending on the picture format.
Audio data is stored using PCM and Dolby digital, which enables higher sound.
Furthermore, multi-angle and multi-language features will also help you enjoy the
more advanced technology of DVD video.
●Viewer restrictions: This feature limits what can be viewed in conformity with the
level of restrictions of the country. The level of restrictions varies depending on

■Engine oil consumption
●The amount of engine oil consumed depends on the oil viscosity, the quality of the
oil and the way the vehicle is driven.
●More oil is consumed under driving conditions such as high speeds and frequent
acceleration and deceleration.
●A new engine consumes more oil.
●When judging the amount of oil consumption, keep in mind that the oil may have
become diluted, making it difficult to judge the true level accurately.
●Oil consumption: Max. 1.1 qt./600 miles, 0.9 lmp.qt./600 miles (1.0 L per 1000
km)
●If you consume more than 1.1 qt. (1.0 L, 0.9 lmp.qt.) every 600 miles (1000 km),
contact your Lexus dealer.
